Node.js v4.0 through v4.8.3, all versions of v5.x, v6.0 through v6.11.0, v7.0 through v7.10.0, and v8.0 through v8.1.3 was susceptible to hash flooding remote DoS attacks as the HashTable seed was constant across a given released version of Node.js. This was a result of building with V8 snapshots enabled by default which caused the initially randomized seed to be overwritten on startup.

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2017:3002 advisory.

    Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network     applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and     efficient, perfect for data-intensive real-time applications that run across distributed devices.

    The following packages have been upgraded to a later upstream version: rh-nodejs4-nodejs (4.8.4).
    (BZ#1476314)

    Security Fix(es):

    * It was found that Node.js was using a non-randomized seed when populating hash tables. An attacker, able     to supply a large number of inputs, could send specially crafted entries to the Node.js application,     maximizing hash collisions to trigger an excessive amount of CPU usage, resulting in a denial of service.
    (CVE-2017-11499)

    Bug Fix(es):

    * The /opt/rh/rh-nodejs4/root/usr/share/licenses/ directory was not owned by any package. Consequently,     when the rh-nodejs4 collection was uninstalled, the directory was not removed. This bug has been fixed,     and the aforementioned directory is correctly removed after uninstalling rh-nodejs4. (BZ#1316626)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

This update for nodejs4 and nodejs6 fixes the following issues:
Security issues fixed :

  - CVE-2017-1000381: The c-ares function     ares_parse_naptr_reply() could be triggered to read     memory outside of the given input buffer if the passed     in DNS response packet was crafted in a particular way.
    (bsc#1044946)

  - CVE-2017-11499: Disable V8 snapshots. The hashseed     embedded in the snapshot is currently the same for all     runs of the binary. This opens node up to collision     attacks which could result in a Denial of Service. We     have temporarily disabled snapshots until a more robust     solution is found.
